Front Disc Brake model (2005) Test Ride flat out

The test ride seems to show there is a rev limiter at
10500 rpm. It also shows if the bike had an rpm dial the
red line would start at 9000 rpm and end at 10500 rpm.
9609rpm develops less power and torque than 8160rpm
I expect rev limiter is in the CDI (electronic ignition) box

5500 rpm is my advised warming up speed.
It's also the maximum speed I would run a new engine in.
It probably takes 3.5 to 5 miles to warm up, dependant on outside temperature.

I would not go past peak power,
the engines power will dramatically drop off above this
(because it's a pushrod OHV engine, not OHC) and increase engine wear.
